Java Tomcat 8 JDBC和Oracle PDB连接问题

java oracle tomcat jdbc

Java Tomcat 8 JDBC和Oracle PDB连接问题,java,oracle,tomcat,jdbc,Java,Oracle,Tomcat,Jdbc,我有一个在Tomcat8上运行的Java8Web应用程序。我在server.xml文件中配置了一个JDBC连接，以连接到Oracle 12c容器数据库 <Resource accessToUnderlyingConnectionAllowed="true" auth="Container" driverClassName="oracle.jdbc.OracleDriver" maxIdle="10" maxTo

我有一个在Tomcat8上运行的Java8Web应用程序。我在server.xml文件中配置了一个JDBC连接，以连接到Oracle 12c容器数据库

<Resource accessToUnderlyingConnectionAllowed="true" auth="Container" driverClassName="oracle.jdbc.OracleDriver" maxIdle="10" maxTotal="25" maxWaitMillis="10000" name="jdbc/LOCALDB" type="javax.sql.DataSource" url="jdbc:oracle:thin:admin/admin123@localhost:1521/DBSVC"/>

尽管存在错误，SQLPlus和SQLDeveloper可以连接到服务和SID，因此连接肯定可以工作。本文（）建议您在使用JDBC和在侦听器配置文件中使用以下属性时可能会看到此错误

USE_SID_AS_SERVICE_listener=on

不幸的是，这不适用于我，它只会将上述错误更改为以下错误：

Caused by: oracle.net.ns.NetException: Listener refused the connection with the following error:
ORA-12514, TNS:listener does not currently know of service requested in connect descriptor

lsnrctl状态的输出显示：

[oracle@bcc0fa014b84 ~]$ lsnrctl status

目前，我不明白为什么Tomcat不能连接到我的Oracle数据库。有人知道为什么会这样吗？我遗漏了什么吗？

lsnrctl状态的输出是什么？更改为使用\u SID\u作为\u服务\u侦听器后创建了什么服务名称？您好！谢谢你回复我。更新了带有请求输出的帖子，但根据我对输出的理解，它显示监听器可以连接服务。我不确定添加USE_SID_as_service_listener后创建了什么服务。我不知道它创建了一个新的服务。您是否尝试过在JDBC URL中使用“127.0.0.1”而不是“localhost”？
